Keeping math formula information for export
by Jairo A. del Rio 07 Jul '25

07 Jul '25

Hi, list. When MathJax and KaTeX output formulas in SVG, they attach data, e.g. Unicode info, math classes, etc. For instance, KaTeX outputs something like that for $1 + 1$: <math xmlns=" http://www.w3.org/1998/Math/MathML" display="block"><semantics><mrow><mn>1</mn><mo>+</mo><mn>1</mn></mrow><annotation encoding="application/x-tex">1 + 1</annotation></semantics></math>1+1 AFAIK LaTeX and ConTeXt don't export to SVG natively and tools like dvisvgm don't know about this information when converting .dvi or .pdf files to SVG. But info is somehow available via tracing macros. In ConTeXt, I get the following log from this file: \startTEXpage %\tracingmacros etc. \tracingcommands\plusone \tracingonline\plusone $1 + 1$ \tracingcommands\zerocount \stopTEXpage Log: (a lot of info...) 7:7: {\Umathfractiondelsize} 7:7: {\Umathfractiondelsize} 7:7: {\Umathfractiondelsize} 7:7: {\Umathfractiondelsize} 7:6: {\Umathskeweddelimitertolerance} (a lot of info...) 7:4: {the character U+0031 1} 7:3: {blank space character U+0020 'space'} 7:3: {the character U+002B 'plus sign'} 7:3: {blank space character U+0020 'space'} 7:3: {the character U+0031 1} ... Also, MathJax and KaTeX can export glyph outlines, which I know ConTeXt already handles with via Metapost and Lua. So, I wonder if such structure (paths + data) can be saved/exported as a Lua table, a SVG file or any other format which keeps the semantic information of math formulas. Thank you very much Jairo

success and a query
by jbf 06 Jul '25

06 Jul '25

The very latest ConTeXt update appears to have resolved any previous issues I was having with color profiles. My log file now reads, as I hoped it would> backend > profiles > profile specification 'Coated FOGRA39 (ISO 12647-2:2004)' loaded from '/home/julian/data/context/tex/texmf-context/colors/icc/context/colorprofiles.xml' backend > profiles > setting 'CoatedFOGRA39.icc' as default 'cmyk' color space backend > profiles > setting output intent to 'Coated FOGRA39 (ISO 12647-2:2004)' with id 'FOGRA39' for entry 1 Thank you! There is a new warning in the log file that I have not seen before (nothing to do with the above). Could someone explain its significance to me? I assume I don't really need to bother about it but I'd like to understand it. csname overload > warning, protection level 3, control sequence 'newcontextversion', properties 'permanent protected', file '/home/julian/data/context/tex/texmf-context/tex/context/base/mkxl/cont-new.mkxl', line 16 (Line 16, BTW is simply \setuplayout ) It repeats a few times in different ways, e.g. csname overload > warning, protection level 3, control sequence 'starttitle', properties 'frozen instance protected', file './prd_Gering30-06-25.tex', line 285 Julian

Hi folks, is it possible to use an externalfigure (blabla.jpg) as a repeated header in a table and if yes, how can I use it? \setupTABLE[][][\externalfigure[blabla]] doesn't work. Thank you for any hint! Greetings Tomás

End-page hyphenation
by John Was 05 Jul '25

05 Jul '25

Hello A long-cherished desideratum is automatic prohibition of hyphenation at the end of a recto page (except for split footnotes, where this is actually quite helpful in forcing the reader to complete the note on the following verso). That was always disallowed at OUP (but allowed at the end of a verso). I've never managed this in plain TeX, so that at the last moment I scroll through the odd-numbered pages putting words in an \hbox if the unwanted hyphen has happened (and one then has to keep an eye out for the rare case where paragraph reflow throws up another problem). Is this feasible in ConTeXt?

Distance between text and footnotes
by John Was 05 Jul '25

05 Jul '25

Hello I would like to optimize the distance between text and footnotes in a standard octavo book at 6 points (absolute minimum 3 points, and trying to avoid going higher than 12 points). Relatedly, the footnotes on a short page at the end of a chapter should be brought up close to the text (6 points). I have been used to doing this manually (adding \VFILL at the end of the last note, which is defined as multiple occurrences of \vfill). Can this be set up in ConTeXt?

Custom background color for \framed inside lmt_text
by Emanuel Han 05 Jul '25

05 Jul '25

I want my custom color rose_color to be applied for background color for \framed inside lmt_text. For fill fullcircle, it works. With predefined colors as green, it works. \starttext \startMPcode color rose_color; rose_color = 1/256(255,204,255); %not working draw lmt_text [text ="\framed[background=color,backgroundcolor=rose_color,frame=on, location=low]{a rose box}",]; %working draw lmt_text [text ="\framed[background=color,backgroundcolor=green,frame=on, location=low]{a green box}",] shifted (1cm,1cm); %working fill fullcircle scaled 2cm shifted (0,3cm) withcolor rose_color; \stopMPcode \stoptext

Bookmark hierarchy
by John Was 04 Jul '25

04 Jul '25

Hello. I'm still in the newbie category with ConTeXt, and am getting to grips with bookmarking of PDFs for the first time ever. The following example gives the correct hierarchy of subordinated bookmarks - part, chapter, and section, each progressively indented in the bookmark column at the left. However, I don't want the parts to have numbers at all, and I want the chapters to be numbered 1, 2, etc. (not 1.1, 1.2, etc.). If I ever go live with ConTeXt, the sections won't have any numbers at all (and I can see how to set this up), but in this default example I would like them also to shift up one decimal place: 1.1., not 1.1.1, and so on. I'm guessing there's an option in \part that I should be invoking, but I don't immediately see what that is (there doesn't seem to be a \startpart...\stoppart to allow the relatively straightforward customization that we get with chapters and sections). Here is the example: \setupinteraction [state=start] \setupinteractionscreen [option=bookmark] \placebookmarks[part,chapter,section] \starttext \part[title=Introduction,bookmark=Introduction,number=off] \noheaderandfooterlines INTRODUCTION \page \noheaderandfooterlines \page[odd] \startchapter[title=First Chapter] \noheaderandfooterlines \input tufte \startsection[title=First section] \input knuth \stopsection \startsection[title=Second section] \input zapf \stopsection \stopchapter \page[odd] \startchapter[title=Second Chapter] \noheaderandfooterlines \input tufte \startsection[title=First section] \input knuth \stopsection \startsection[title=Second section] \input zapf \stopsection \stopchapter \page[odd] \part[title=PART II,bookmark=Part II,number=off] PART II \noheaderandfooterlines \page \noheaderandfooterlines \page[odd] \startchapter[title=Third Chapter] \noheaderandfooterlines \input tufte \startsection[title=First section] \input knuth \stopsection \startsection[title=Second section] \input zapf \stopsection \stopchapter \page[odd] \startchapter[title=Fourth Chapter] \noheaderandfooterlines \input tufte \startsection[title=First section] \input knuth \stopsection \startsection[title=Second section] \input zapf \stopsection \stopchapter \stoptext Best wishes John *🇪🇺 * Слава Україні! * 🇺🇦* <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_cam…> Virus-free.www.avg.com <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_cam…> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>

\setupwhitespace[default]
by Bruce Horrocks 03 Jul '25

03 Jul '25

Is default a valid option for \setupwhitespace? It's listed in the wiki page but gives an error when used, e.g. \starttext \input knuth \par\thinrule\par \setupwhitespace[big] \input knuth \par\thinrule\par \setupwhitespace[default] \input knuth \stoptext Wiki link: <https://wiki.contextgarden.net/Command/setupwhitespace> — Bruce Horrocks Hampshire, UK
